摘要： The present disclosure is concerned with an oral hygiene implement having a longitudinal axis, a carrier element mounted for driven movement, a motion transmitter that has a first end for transferring a drive force to the carrier element, which first end is provided at a position being offset from the longitudinal axis, and the motion transmitter has a second end positioned essentially on on the longitudinal axis or is arranged for being positioned essentially on the longitudinal axis during operation, wherein the motion transmitter has a first coupling part comprising the first end, which first coupling part essentially extends along a centre axis arranged at an angle with respect to the longitudinal axis, and a second coupling part comprising the second end, which first coupling part is fixedly connected with a first connecting portion of an elastic pivot element that allows that the first coupling part and the second coupling part can pivot with respect to each other at least in a first pivoting plane spanned by the longitudinal axis and by the centre axis, and wherein the first coupling part is made from a plastics material, including reinforced plastics materials, having a Young's modulus of at least 5000 MPa or from a metal material, and at least the first connecting portion, in particular the whole elastic pivot element, is made from a plastics material having a Young's modulus of not more than 3000 MPa, optionally of not more than 1000 MPa, further optionally of not more than 500 MPa.
